VATS Problem

Tried to start 93 this morning, Got the STARTING DISABLED DUE TO ANTI THEFT message. Tried diffrent key with same result. Gonna check resistance at harness connector with key in in the morning and do the resistor deal if needed, but my question is if not the wiring in the steering collum problem what is the next most likely culprit? VATS module failure? I know, check the codes.
